Functioning of the upper extremity in persons with late polio

Area of Science:

• Neurology
• Rehabilitation Medicine
• Public Health

Background:

• Late effects of polio impact many individuals, with unclear involvement of upper extremities.
• Understanding arm and hand function in polio survivors is crucial for targeted care.

Purpose of the Study:

• To describe upper extremity involvement in individuals attending a polio clinic.
• To assess self-reported arm and hand functional problems in polio survivors.

Main Methods:

• A 1-year study of community-dwelling individuals at a polio clinic.
• Clinical assessments included electromyography and muscle strength.
• A questionnaire evaluated perceived problems in arm/hand activities.

Main Results:

• 186 individuals were assessed; 96% had post-polio syndrome.
• Upper extremity polio involvement was common and often clinically unstable.
• Grip force correlated with perceived problems; bimanual activities were frequently problematic.

Conclusions:

• Polio involvement of the upper extremities is highly prevalent among survivors.
• Perceived functional problems did not consistently correlate with objective polio findings.
• Polio survivors may need further assessment to identify intervention needs.
